8 Claims.

1 This application is a division of application, Serial No. 400,870, filed July 2, 1941, now Patent No. 2,393,973.

The present invention relates to winding machines for winding yarn, thread and similar textile materials into packages such as cops, bobbins, pirns and the like. More specifically, the

invention consists in means for automatically applying identification marks to the wound bobbins.

In the present specification and claims the term yam is employed to indicate all kinds of attenuated material and the term bobbin is used to designate the wound package whatever its form or character.

It is a common practice in textile mills to identify filling yarn by marking the bobbins with crayon or chalk to indicate different types and counts of the yarn and also to identify the machine or department in which the yarn is processed or handled. Usually, the operator oi. the machine marks the yarn on the bobbin by drawing a piece of chalk or crayon over the surface of the bobbin, but this operation has certain disadvantages as it is liable to cause the chalk dust to infiltrate into the mechanism of the machine to interfere with its proper functioning.

The practice of marking the bobbins as now Most mills handle more than one count of yarn at the same time and as the counts must be kept separate it is an object oi. the present invention to provide automatically-operated means for marking the bobbins as they are delivered from the machine with one or more distinguishing colors to prevent mixed counts from being woven in the loom; and iurther, to trace the steps in the processing of the yarn in different departments of the mill to correct defects or deficiencies in its manufacture.

Another object or the invention is to provide bobbin-identifying means which may be employed as an attachment on winding machines in which the bobbins are dofied either manually or automatically upon completion or the winding.

Another object of the invention is to provide a device which may be applied to winding machines to mark the bobbins produced therein with diiferent colors applied thereto.

Another object of the invention is to provide means for marking the bobbins with different colored chalk or crayons after they have been doffed from the machine and during their delivery therefrom.

Further objects of the invention are set forth in the following specification which describes a preferred form of construction of automatic bobgenerally used is for the purpose of preventing bin-identifying m a as illustrated y the mixed counts of filling yarn going to the same ompa yin d awi s. n t dr w n s:

When chutes to a marking device at one end of the mathe bobbins are properly marked the weaver can chine; discover if mixed yarn is furnished to the weave Fig. 2 is a side elevation of the essential mechroom and place the responsibility in the windanism of a bobbin-winder showing the relation ing room or other department of the mill where 40 of the winding bobbin to the chute through the yarn was processed or handled, In oth r inwhich it is delivered to the conveyor belt to be stances, by applying several distinguishing marks transpo t p t the marking v c to the yarn on the bobbin its progress from the While the present invention y be pp to source can be followed and when poor r imperuse with either manually-operated or automatic fect bobbins reach the weave room they can be winding machines, it iS e n des ibed a d traced to the machine in which they were wound or to the department in which the yarn was processed. In some cases different types or counts of yarn are wound'on different spindles of the same machine. and the bobbins may becomemixed through carelessness of the operator, as by the dropping of bobbins on the floor or by incomplete emptying of the collecting boxes for one type of yarn before bobbins of another type are placed therein.

illustrated in connection with a machine of the type disclosed in United States Letters Patents No. 2,257,651, dated September 30, 1941, and No. 2,302,715, dated November 24; 1942. The machines illustrated in these prior patents are completely automatic for donning empty cores or yarn-carriers, winding the yarn thereon, and dofling the bobbins as they are completed. It is therefore desirable that machines of this type shall be further adapted. for marking the bobbins a V r 3 automatically to identify them after they have been delivered therefrom. On the other hand,

it is to be understood that the present invention is not limited to use with automatic winding machines, but may be applied to other types of winders for marking the bobbins as they are dofled manually. 7

Referring to the drawings, the frame or casin: of the winding machine is indicated at 2 and projecting from bearings therein is a rotary winding spindle 3 at the end of which is a cup-shaped member 4 for receiving the head h of a wooden core or bobbin D such as used in automatic fillwhich overlap at their forward ends. In this way the bobbin grows by longitudinal extension, being formed with a conical base, a cylindrical body portion and a tapered or conical tip end.

- The thread-guide i is carried on a reciprocable traverse-rod 15 mounted to slide longitudinally in a bearing in the frame or casing 2. The traverse-rod i is reciprocated longitudinally in its hearing by a suitable cam or similar means enclosed within the frame or casing 2 of the ma.-

' chine, but not herein illustrated as such traversing mechanism is well known to those versed in the art. -The yarn y delivers from its source of supply, supported above the machine but not herein shown, and feeds to the bobbin through an eyelet I! in the thread-guide ll. Connected to the thread-guide Ill is a rotatable contact-disk or traverse-wheel 20 mounted on a sleeve-like nut 2| which is interiorly threaded to engage the screw-threads 22 on the traverse-rod l5. It will 'be understood that the thread-guide i0 is positioned adjacent the rearward or butt end of the a return stroke to the left, as viewed .in Fig. 2,

the periphery of the wheel will contact the yarn wound on the bobbin to turn the nut 2i through a part of a rotation to feed the guide forward to a slight extent along the traverse-rod l5. This method of advancing the layers of winding along the bobbin by the intermittent feed of the thread guide is illustrated and'described in the prior patents referred to above and is well known to those versed in the art.

At the completion of the bobbin the threadguide ill will be positioned at the forward or tip end of the bobbin when at the furthermcst limit of its forward stroke and at this point the guide, or a part connected therewith, engages a stop or abutment to move the latter to cause actuation of the stopping mechanism of the machine; this mechanism being employed generally in machines which require manual dofllng and donning. In automatic machines such as described in the pat.-

ents referred to"above, the completion of the bobbin effects initiation of the operation of means for doifing the wound bobbin, donning an empty core or yarn-carrier, severing the yarn from the dotted bobbin, attaching the end of the yarn to the empty carrier, returning the thread-guide tov s -4 initialwindingpositiomandagainstartingthe winding operation. The automatically-Operated mechanism for performing these functions is described in the prior patents before mentioned and is not referred to specifically herein as it forms no part of the present invention. Sufiice it to state that as the wolmd bobbin B is doifed by releasing it from the driven winding spindle 2, it drops by gravity into a chute 23, Fig. 1, arrang thercbelow.

The wound bobbins may be marked with several different colors, for example red, yellow and green, to indicate the size or 001111; of the yarn and other particulars such as the department in which the yarn was spun or processed, or in other cases the particular machine in which the bobbins were wound. The colored markings remain on the yarn when it is woven into the cloth, but

when the fabric is later processed or finished,

the color, being fugitive, will disappear on treatment with water or other liquids.

The present drawings illustrate a device for applying identiflcatiomindicia to the bobbins by the use of crayons. With this form of construction of the invention the bobbins .are discharged through the chutes 23 onto a traveling endless conveyor belt 25 extending longitudinally of the gang machine beneath the plurality of winding units or heads indicated by the reference character 26. The conveyor belt 25 is traveled in the direction indicated by the arrow in Fig. 1 by ,along and discharge them into a box or other receptacle 30 at one end of the machine. Arranged abovethe belt 25 adiacent one end thereof are a seriesof crayon-holders 3i pivoted on a bracket 32 and held in vertical position by means of a spring 33. As the bobbins B are carried along by engagement with the battens 29 on the belt 25 they pass under the crayons 3'4 held in the holders 3i and rock the latter into the position indicated by dotted lines in Fig. 1, thereby causing the crayons to mark identifying colors upon the yarn on the bobbins. After the bobbins have been marked in this manner they are discharged into the box 30 to be transported to the weave room or other department of the mill.

It will be observed from the foregoing specification that the presentinvention provides means ture and arrangement of the parts of the device and the manner of applying it to use without departing from the spirit or scope of the invention. Therefore, without. myself in this respect, I claim:

1. In a winding machine, the combination with a. plurality of winding of an endless conveyor arranged therebelow, means for traveling the conveyor in a horizontalpath to adapt it to receive packages of yarn dolled from the. winding units, and means adjacentv the conveyor for contacting the packages as: they are traveled thereby to mark the yarn on the packages with identi fying indicia.
